Researchers from Trinity College Dublin have discovered a patch of land in an ancient valley on Mars that appears to have been flooded by water in the not-too-distant past. In doing so, they have pinpointed a prime target ...
The invasive species Carex kobomugi, or Asiatic sand sedge, was first found along the East Coast of the United States at New Jersey's Island Beach State Park in 1929. The species is aggressive, outcompeting native vegetation ...
An astronaut aboard the International Space Station (ISS) used a long lens to document what crews have termed one of the most spectacular features of the planet: the dunes of the Namib Sand Sea.
Sand dunes pull double duty—offering a visual treat both for their undulating curves and their ability to attract birds and other wildlife, while affording protection from storm surges and the threat of rising sea levels.
The recovery of beaches across the South West following the severe storms of 2013/14 is to be explored as part of a major new research initiative.
This image of dark dunes on Mars was taken on Feb. 6, 2016, at 15:16 local Mars time by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter. These dunes are influenced by local ...
Some of the wind-sculpted sand ripples on Mars are a type not seen on Earth, and their relationship to the thin Martian atmosphere today provides new clues about the atmosphere's history.
Sand dunes cover much of this terrain, which has large boulders lying on flat areas between the dunes.
Rolling sand dunes in the expansive Rub' al Khali desert on the southern Arabian Peninsula are pictured in this image from the Sentinel-2A satellite.
One day, most likely, humans will visit Mars and begin to unravel its geological history and even determine if anything once lived there.
